Local And Remote Database Sync
Dec 5, 2009
I'm posting this in the vb.net as I will be using visual studio to perform the task. So here is what I am trying to achieve or at least achieve it more efficiently than what I am doing now.
So I have two identical database setups, both with a table , let call it table tblUsers. The local database is edited through vb.net and is a Access database. The second database is hosted on a remote server and is a MySQL databse.
Currently I have no problem connecting and editing either database through vb.net. I'm using OLE DB to connect and handle the Access database and ODBC 5.1 to connect and handle the MySQL database.
Here is what I would like to do:
User opens the program Presses the "update local" button
The program updates the local database to whatever the remote database is The user uses the program to edit fields in the local database
When done, the user presses the "Update remote" button and the remote database fields that have been edited with the program in the local database will be updated to the remote database.
Currently, the only way for me to do this is to go line by line in a for next and use a command builder to compare each field and update that way.

I am making a VB.NET application that can download/backup the database that is currently on a remote server. I have Remote Server IP,Username,Password and Database name. I am also able to connect to it. But I don't know what to do after connecting to it. I don't know what all files are need to be backed up. (I think database and log file both must be backed up, I am not sure).

Scenario: I want to develop an application.The application should be able to connect to my remote server and download data to the local disk , while downloading it should check for new files and only download the new ones simultaneously creating the required(new) folders.
Problem: I have no idea how to compare the files in the server with the ones in the local disk.How to download only the new files from the server to the local disk?
What am thinking?: I want to sync the files in the local machine with the ones in the server. I am planning to use rsync for syncing but i have no idea how to use it with ASP.NET.

I put together a small app I want to use on my local network for service monitoring across a few of my servers.
I'm using vb.net express 2010 with system.serviceprocess imported The problem I am having is that my code only seems to work locally, and will not retrieve the service data for any server on my network.
For example, my local machine is called "office-pc", and when running the app on it, I get all the service information.
Dim localServices As ServiceController() = ServiceController.GetServices("office-pc")
For Each localservice As ServiceController In localServices
ComboBox1.Items.Add(localservice.DisplayName)
Next
But, if I want the service info from my web server called "casper", I use the same code, but i change the GetServices() parameter like so;
Dim localServices As ServiceController() = ServiceController.GetServices("casper")
For Each localservice As ServiceController In localServices
ComboBox2.Items.Add(localservice.DisplayName)
Next
After a few seconds delay, nothing happens, ComboBox2 remains empty.
It was my understanding that GetServices() would get the local machines service info unless a machine name was specified, which in both cases is true.
So why isn't it working? Do I need to set something up on the network servers first?

In PHP you can use fopen(Path) to read from a file. The Path can be either a local file (in the usual formats /etc/file or c:file.txt) OR it can be a URL in which case PHP will open a http connection and read from the remote location
I'd like to achieve the same in VB.Net. I'm not aware of any framework function which will achieve this.
I'm currently pattern matching the path against a Regex for a valid URL - If I get a match, I open the file using a httpwebrequest otherwise I try to use the local file system.
Private Function RetrieveBGImage() As Image
Dim Ret As Image
If Not (IsURL(_BackgroundImage) Or IsLocalFile(_BackgroundImage)) Then
Throw New Exception(String.Format("Unable to load from uri ""{0}""",
[Code].....
NB: I'm aware that the logic above is inefficient and actually ends up calling IsURL() more than it has to

I am looking for a way to determine whether a file spec that I provide is local or remote. I am using VB2008. I have a VB6 app that does this by using the PathIsNetworkPath API call, but I am hoping that I can use the .NET framework instead with VB2008. Google gives lots of results on how to determine if a network path is available, but not specifically what I want.

i'm working in VB.net to create a program that checks the text in a remote text/html file against a local text file, and if the do not match, the program then does something. I keep getting an exception and i can't figure it out.
Here are the details of the exception:[code...]
I'm not at all used to working in VB, and i'm not sure if i did that HTML right either, so that could be the problem.

I have an off-line project. User uses a laptop to input data off line into local SQL server express. Once connected to domain (on line), local data will sync with remote SQL server using sync framework. (It is done, works fine)One job left:Since another user used another program to update some tables in remote SQL server, such as CUSTOMER, SHIPINFO, my off-line program need to update these new data once connect to domain.Here is what I design in Pseudo (take CUSTOMER as example)
1) In remote SQL server, create a store procedure (sp_customer) to select all CUSTOMERS
2) In application, create a dataset (dst_customer) based on sp_customer
3) Insert all customers data which is in remote SQL server but not in local SQL server based on CUSTOMER_ID

The following steps give a Guest shutdown policy.
1- Click run, and type the gpedit.msc, to start "Local Group Policy Editor".
2 -Expand "Computer Configuration" -> "Windows Settings" -> "Security Settings" -> "Local Policies" -> Then click "User Rights Assignment".
3- In the Policy window, Select "Force shutdown from a remote system", double click it, it will pop a properties window.
4- Click "Add user or group button", add a user and name it Guest.
I need to know if it's possible to manipulate and add the user or group programmatically. I'm using Visual Basic 2008.

I used .NET Framework 1.1 in C/S project before. Now I have updated the project to use .NET Framework 3.5 without modifying source code, but I have found that : the Remoted DateTime values can not be converted to the equivalent local time of a remote computer that is in a different time zone. In .NET Framework 1.1, the DateTime values can be converted automatically.

I am attempting to call a remote modem using a local modem connected via USB. Programming language is VB.NET and I am using the SerialPort control to talk to the modem.
Communication is as follows:
I send: ATZ0[CR]
Modem responds: ATZ0[CR][CR][LF]OK[CR][LF]
I then try to dial a number:
I send: ATDTnnnnnnnnnn[CR] where nnnnnnnnnn is a valid number
The modem responds with:ATDTnnnnnnnnnn[CR][CR][LF]ERROR[CR][LF]
All other commands seem to work without any issues
For info the modem is a MultiTech MT5634ZBA-USB-V92
If I use hyperterminal and type the same commands in it works as expected and dials the number, so it must be something I am doing in my code, possible some setup in the SerialPort control

I am trying to copy a table from a network database to a local database. I used DAO and could check if the network table existed using a function that tried to assign a TableDef object to the table in question. If there was no error then I assumed that the table existed and the function returned true...Or it would error out and return false.I could then proceed with the copy or not as the case may be.I am converting the code to ADO.net and need to know how to check for a table.
